Interaccions planta-planta en gradients d'estrès en ecosistemes freds Plant-plant interactions along stress gradients in cold ecosystems

Description: [cat] En aquesta tesi presento quatre capítols, en els quals es discuteix com diferents espècies subarbustives interactuen amb plantes coexistents, sota règims variables d’estrès. Aquesta recerca ha estat centrada en ecosistemes de gran valor ambiental, ecològic i de conservació, i alhora sensibles ...

Tree sapling responses to 10 years of experimental manipulation of temperature, nutrient availability, and shrub cover at the Pyrenean treeline

Description: Treelines are sensitive to environmental changes, but few studies provide a mechanistic approach to understand treeline dynamics based on field experiments. The aim of this study was to determine how changes in the abiotic and/or biotic conditions associated with global change affect the performance...

Plant community composition affects the species biogeochemical niche

Description: Nutrients are essential for plant development, and their availability and stoichiometric ratios can influence the composition of plant communities. We investigated the possibility of the reverse influence: whether the conditions of contrasting species coexistence determine foliar element concentrati...

Abrupt changes in the composition and function of fungal communities along an environmental gradient in the High Arctic

Description: Fungi play a key role in soil–plant interactions, nutrient cycling and carbon flow and are essential for the functioning of arctic terrestrial ecosystems. Some studies have shown that the composition of fungal communities is highly sensitive to variations in environmental conditions, but little is k...

Four years of experimental warming do not modify the interaction between subalpine shrub species

Description: We thank Clara Borrull, Noelia Seguer, Estela Illa, Victoria Lafuente, Elena Lahoz and Santiago Pérez for their field and laboratory assistance. We are grateful to CCiT of the University of Barcelona for the use of their facilities and their technical assistance. This work was supported by Conselh G...

Changes in nutrient concentrations of leaves and roots in response to global change factors

Description: Global change impacts on biogeochemical cycles have been widely studied, but our understanding of whether the responses of plant elemental composition to global change drivers differ between above- and belowground plant organs remains incomplete. We conducted a meta-analysis of 201 reports including...

Regulation of Nitrogen Fixation from Free-Living Organisms in Soil and Leaf Litter of two tropical forests of the Guiana shield

Description: Biological fixation of atmospheric nitrogen (N2) is the main pathway for introducing N into unmanaged ecosystems. While recent estimates suggest that free-living N fixation (FLNF) accounts for the majority of N fixed in mature tropical forests, the controls governing this process are not completely ...
